Application i-led March 19, 1924. Serial No. 700,817.

T0 all 'whom t Wwy/ concern liiie it known that I, fllnwiN H. BRODEN, a citizen of the United States.; and resident of Edgewood Borough, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pliers; of which the following is a specification.

This invention relates Vto wire ycutting pliers; and rhas foritspa-rticular object the provision 'of such pliers having safetynieans for holding the wire that has heen out.

Another object is to adaipt such safety ineens to the wel-l known and acceptedforin of button pliers now in use, without ina-V terially changing their forni or, adding to their weight.

A. further object is to lprovide pliers havifngthe novel design, constructiomand coinhi'nation ofparts hereinafter described and illustrated in the accompanying drawings.

Heretofore pliers of this class havebeen provided with outti1ig notclies and `have come int-o general use., However, oftentimes the wire when cut will 'fly and ystrike either the operator or one of his fellow worknien, and ine-ny times has `caused serious injury to theireyes land other parts vof their bodki'es Especially is this true in cutting loa'r edwire. i

iVithin the last few .years those. skilled ih this art, spurred on by the numerous safety :first campaigns; have attemptedl to provide pliers of this class withineans for holding out wire. Howeven the pliers. heretofore pievided with mme ipe holding ure-eut wire have been thoroughly tested and d i'sL carded'. as unsuccessful.

The present oliers are composed of few parts, lare of suln'stantiially the saine weight and size ol' the standardpliers now in use, and are not weakened. in any inann'er hy the addition of the safety ineans.

Referring` inore particularly 'to the drawings, the letters A and B Vdesigpiate the two limbs of 'iny iniproved pliers; which are lcons't'ruted to forni 'gripping jaws` handle portions 1l, and disk-hearing joint portions 5. The disk-hearing joint portions 5 'are forine'd in the usual inanner hy forming an enlarged circular hearing disk portion loetween the jaw or head 3 andthe handle 41 of each liin and cutting said disk portions away to forni the usual interlocking joint, pivot-ally held together foy a pivot pin l6.

The portions 5 also forni what may he terined Cutting jaws 'and 'are out away to forni iro't'chfes'or recesses 7, 8 and 9, the inner edges of which `:tot as cutting blades to out wire or thelike, the notches in the portions. 5 being errange'd in pairs and oooperting to forin 'continuoils grooves or recesses for th'e reception of the wire to be cut.

A wire elalnpi'ng plate lO is positioned on he outside fa'ce of eaeh ofthe hearing' portions or cutting jaws 5. The plates 10 are pivotally inoun'ted in position on .pivot pin 6a whieh passes centrally through the inin pivot (i, and y'therefore are movable ahoiit zi common axis with liinhs A and B. Each of the plates l() is provided on its inner sido faoewi'th a recess l2 in which is in'ouhted a Asprii'ig 14 idapte'd to engage a pin 'll secured `in the respeotive liinhs, thus providing' a yiel'dahle connection between the plates 10 and linihs A 'find B, wherehy the plates will yield to lpermit enggeinent with varying` sizes of wire.

The phi'tes l0 `are provided with notches l5; 1G end li' cor'respending` with the notches 7; S ond 9 i`n the disks 5; and tho notches 15, 1G eiid 17 are adapted to aline with the notches 7, 8 end 9 when the tool is in wire receiving position to forni a continuous wire reeei'ving` recess or slot.

rPhe side walls of the notches 7, 8 and 9 are square, as are also the side walls of the 'notches 15, 16 and 17, so as to form wire gripping faces for clamping the wire.

In operation, when the pliers are moved to open position the limbs A and B and plates 10 will all move about their common axis so as topassume a position in which the notches 7, 8 and 9 of the opposite disk or cutting jaw portions 5 will move intoalinement, and the notches 15, 16 and 17 of the plates 10 will also aline, respectively, with the notches 7, 8 and 9 so as to form continuous wire receiving recesses or slots.

When the limbs A and B are moved to closedor cutting position the disk or cutting jaw portions 5 will rotate in opposite directions so as to bring the cutting edges of the recesses or notches 7, 8 and 9 into cutting engagement with the wire, and the plates 10 will move in a direction opposite the disks 5 which they abut, due to their being operatively connected by the springs 14 to the limb integral with and extending from the opposite disk, so as'to cause the side walls of the notches 15, 16 and 17 to engage and force the body of the cut wire against the side walls or faces of the recesses or notches 7, 8 and 9, thereby clamping the main body of wire and the severed end in the recesses 7, Sand 9 and preventing movement of the wire from cutting position.

The spring 14 which co-operates with the pin 11 to form a yieldable operative connection for the plates 10 with the limbs A l and B is adapted to yield so as to permit the plates 10 to operate against any size of Wire within the limits of the cutting jaws.

In Fig. 9 I have shown a modified form of clamping plate 10 in which the recess or depression l12 is omitted and an opening 12"L is provided for fitting over the pin l1 and for receiving the flexing end of a leaf-spring 14a formed integral with the plate or welded thereto a-s desired.

It will be understood that while I have described and illustrated my invention as applicable to wire cutting pliers, it may readily be applied to a cutting tool in which the gripping jaws 3 have been omitted,

l that is, to a toolcomposed of a pair of limbs which terminate with the notched disks or cutting jaws 5. Other modifications in design and construction. may also be made without departing from the scope of the appended claims.

I claim- 1. In a cutting tool, a. pair of cutting and `gripping members relatively movable about a common axis, and an independent grip ping member (3o-operating, with at least one of said cutting and gripping members and rotatable about said common axis.

2. ln a cuttingtool, a pair of cutting and gripping members relatively movable about a common axis., and independent gripping members co-operating with each of said cutting and gripping members and rotatable about said common axis.

3. Pliers comprising a pair of limbs relatively movable about a common axis, said limbs each comprising a jaw portion, a handle portion, and a disk joint portion, said disk joint portions being arranged side by side and pivotally joined by a suitable pivot pin, said disk portion of each limb being provided with wire cutting notches, the notches of each disk being adapted to aline with the notches of the other disk when the pliers are in open position, and a gripping member co-operating with at least one of said disk portions and movable about said common axis to grip the article beingI cut.

4;. Pliers comprising a pair of limbs relatively movable about a common axis, said limbs each comprising a jaw portion, a handle portion, and a disk joint portion, said disk joint portions being arranged side by side and pivotally joined by a suitable pivot pin, said disk portion of each limb being provided with wire cutting notches, the notches of each disk being adapted to aline with the notches of the other disk when the pliers are in open position, and independent gripping members co-operating with each of said disk portions and movable about said common axis to grip the article being cut at both sides of the point of cutting.
